I have compared my performance chip review to others I have read and have this it say. Othes said there were small performance improvemance and I agree, but the change in shift pateraneces is a small improvance the biggest gain is in gas mileage. You need to buy 91 ocaaine or better fuel but my car went for 18 city to 20 and 26 to 30 MPG. I have made some other changes to my car it has a K&N Cold Air Inatke and a Flowmaster Exhaust installed. I estamate the HP has been changed from 195HP to 245HP between all 3 instalations in all I recomend the installing the Module ICE

DiabloSport inTune i2 Tuner Reviews


It did the job

Reviewed By Monty D (GRAND ISLAND, NE) Reviewed for a 2007 Ford Mustang —2/9/2016 4:55 AM

I used this tuner in my 2007 Ford Mustang GT. Loved that it let me set my tune and remove the speed limiter. NOTE* Make sure you update it before trying to install in your vehicle. I had to run the update twice to get my car to run correctly. More user error than any part on the tuner
